AUTOMATIC FINGERPE-INT MACHINE.

Application filed August 19, 1922.

TO ((ZZ whom 'it may concew:

Be itknown that I, ALFRED CHARLES O'rro BOOK; a citizen of the UnitedStates of America, residing at Brooklyn, County of Kings and State ofNew York, have invented new and useful Tmprovements in AutomaticFingerprint Machines, of which the following is a specification.

This invention relates tomachines whereby the print of a person s ngermay be readily and accurately obtained.

The object of the present invention is to provide improvements upon themachine as set for-th m applications for patent by Charles F. GrlassSerial Number &18,857 filed October 23, 1920, and another Glassapplication Serial Number 320593 'filed August 29, 1919. 1

The main object of the invention is to provide an automaticallyOperating machine of the character indicated.

A further object is to provide timing mechanism whereby the heating ofthe impressed surface may be determined and regulated.

A further object is to provide means for automatically returning theOperating handle to normal position after it has been moved to itslimit, thus eliminating the care and skill prevously required inmachines of this character.

Other and ancillary objects will appear hereinafter.

Fig. 17 is a diagram of the electric connections of the heater coils. e

Referring to the drawings, a:-cas11g provided with a base' ll and sides712 houses the mechanism. The top 13, 'being Secured to the sides byscrews 1 1, is provided with a glass insert 15. for the purpose ofallowing heat generated within the casing to escape therefrom. Rubberknobs 17 may be used if desired to prevent the casing from marring thesurface on which it is placed.

A lrawer18 is used to catch the unused Openings 16 are provided pigmentand is slidingly disposed in the base e of the casing A handle 19permits theready withdrawal from the casing. e I

A housing 20 attached to the rear of the casing 12 enoloses the gearspreventing dust or other foreign matter from obstructing the y operationof the gears;

The operatlng handle 21'is capable of movement in a guide way bengarcuately shaped. Plate 23 is removably Secured to the side of thecasing 12 by screws or the like 24:*permitting th'ereby ready access toa i A plate member 27 hinged to the'interior of the `'side at 28provides a meansfor varying the tension of the spring 29 as will bedescribed later. .Thismember is provided ment of the pawl 34. The pawlconsists of a lever pivoted at and provided with an outwardly extendingknob 36 midway of the lever and operated ina slot 37 formed in the sideof the casing. It willthu's be observed 'by li fting the knob 36,consequently lifting the lever 34 out fromthe notch 3201: 33 the member27 may beturned about 'its pivo-tal point 28 thereby varying thestrength 'of the coil spring 29 'which is attached 'thei-eto by a screw146 shown in Figure 2.

'Secured to the top 'of the casing 'is a hop-' per 38 provided with acover "39 pivoted at 40 and adapted 'to contain a powdered pigment."This" hopper extends horizontally acrossthetop ofthe casng and issecured to .the sides 'by means of 'screws 41 or the like.

The means for discharging pignent from the hopper consists of a slidemember 42s'hown more particularly in' Figur-e 14. The slide member isprovided with an elongated s'lot 43 extending longitudinally thereo'fwhich s'adapted to 'register with the outlet43' of the hopper. A lug 44downwardly eXtencl ing is formed ntegrally with the slide memher 42. Ap'late 45 serves as a guide forthe member 42, and 'is also provided withan opening '46. *A lever 47 ispivoted at 48 on' .the under ;side of thehopper 38 and extends tr-'an'sversely thereof. Approxinately midway 'ofits length an opening 49 is formed through which the lug 44 of the slidemember42 is adapted to extend. A finger 50 on thelever 47 moves 'in aslot 51 formedin 'the Side of the ca sing. i

A lever 52 pivoted at 53 to the outside of the casing is adapted to movethe finger 50, 'being provided with fingers 54 and 55 between which thefinger 50 'is disposed. The lower en'd 56 'of the lever 52 :issoarranged to be in the path 'of travel of the Operating handlel '21, sothat when the lever 21' comes in contact with 'the lever 52, the'samewill be rotated 'in a clockwise direction, thereby movi ig the finger 50"back to normal position.

A retainingmember is provided to .hold

' the impression surface 80 compri'sing a base '57 'and 'aspring-pressed retainer 58 *pivot-ed 'at "59 and'GO "to 'the base beingyieldingly held thereagainst by thesprng members 61. The 'retainer 58 isprovided with a finger 62 and a square opening 63. The impressionsurface which-may be paper or other suitable 'material is *placedbetween' the retainer 58 and the base '57, "Showing through. the opening 63.

Pivoted to the base 57 of the retaining member at 64 is the angularextension 65 ot the lever 66. The lever 66 isprovded with a lug 67 atone end thereofand a lug 69' at the other end. v The Operating handle 21is Secured to the lever 66 being rotatably' mounted onthe-rod 68. Thelever 66 is also pivoted to a support 70 at 71.

:Pivoted to the Iupper portion of the casmg is a lever 72 pivoted at 73and providedwith recesses 74 and 75. By the movement of the Operatinghand1e'21, the rod76 which is attaohed to the base of'the impressionsurface retaining member, will strike ,against :the r recesses 74 `and 75 and 'be thus prevented 'from being *returned to normal position.

second 'lever 77 pivoted at 78 'provides a rest v for the end of lever72011 lug 77 -andcre *ates therebetween a gu de for the rod 76.

During such movement of the rod 6, 'the lug 79, which is attached to'the base ;37 'of the retaining member, will come in contact with thedownward extendinglug 44 ?of the *sliding 'member 42 thereupon moving'the same. In this manner pigment s discharged' from the hopper 38 andto the impression surface 80.

A support 81 of insulating material is se- `-c ured to'the side of thecasing by 'screws 82 or 'the like. the support. Pi-votedto said supportare levers 83 and 84,'at points 85 and 96 respectively, the lever 83being disposed beneath *the lever 84 and ozt'angular i ormation. A` fiatsprng-86 tends to force the lever'in a 'counter oloclwise direction asviewed 'in Fig. 10. Pivoted to 'one end of this lever at 89 is a link 87which is provided with an elon- -gated slot 88. Slidably disposed in theslot 88 .is the roller 93 rota tably mounted on a bolt 94 in one end ofan angular-shaped The pla-te 23 forms a cover for lever 90, the lever ispivoted to a support be pointed out later.

The lever 84, angularly shaped ..and piv- -'-o ted .to'the support81'at96, is provided at' H -one end 'with a. hool portion substantiallyL-.s'haped as at 97.` An abntment '98 limits 'the movement ofthe lever84 in one direction and'the coii spring 99 attached to the lever at 100and 'to' the'support 81. at lOl The lever 102 is pivoted t-o'a'brac-lret103, Secured to 'the 'end of the casing b .screws or the like 104, at105; tatably mounted &on the end ;o'fthe lever 102 ?etj-10% and isadapted 'to bear 'against-"titre -maintains the lever against theabutment 98. 9

A roller 106 'is roend of the lever 83 and to move the 'same in aclockwise direction. The roller 106 is also adapted to bear against theunder side of lever 84 when the lever 102 is rotated in a clochwisedirection.

The lever 107 pivotally secured at 108 to the lever 102 between its endextends downwardly, and is adapted to be moved by the lever 66 throughthe medium of the lug or extension 67. A fiat spring 108 maintains thelever 1 07 outwardly and in proximity to the extension 67 so that whenthe lever 66 is moved in a counter-cloclnvise direction the extension 67will bear against the end of the lever 107 moving the same upwardly. Theroller 106 is adapted to bear against the under side of the lever 84which will be moved in a counter-clockwise direction, whereupou the LShaped end 97 will be locked in the 'otch 109 of the lever 83. r

Secured to the support 81 is a strip of metal 110 :t'astened thereto byscrews or the like 111. On the opposite side of the support 81 aresecured at points 114 and 115 two wires 112 and 113, by means of nuts116 and 11'?. The wire 113 is adapted to con vey an electric current tothe metal strip 110, the current passing through the screw 111, whilethe wire 112 is adapted to convey an electric current to the lever 84through the pivotal connection 96. It will thus be seen when the lever84 is brought in contact with the metal strip 110 a circuit will beformed.

Formed integrally on one side of the casing is a curved metal strip 118provided with a plurality of corrugations 119 over which rod 76 isadapted to ride when the operating handle is moved in a counterelockwisedirection. These corrugations serve to spread the pignent upon theimpression surface and to jar there'from any unnecessary pgment, whichwill fall into the drawer below it.

Vertically disposed at one end of the casing is a block of insulatingmaterial 120. An angular-shaped bracket 121 is secured to said block bybolts 122 and nuts 123. A screw 124 secures the bracket 121 to one sideof the casing. A bolt 125 provided with a washer 126 extends through anarcuatelyshaped slot 127 forned in the side of the casing, and heldagainst movement by the nut 128. It will thus be seen by loosening thenut 128 the block 120 may be moved forwardly or rearwardly, the screw124 serving as a pivot.

A plurality of small heater coils 129 are secured to one side of theblock 120 being wound about screws 130. The ends of the coil 129 areattached to binding posts 131, which are secured to the block 120 nearthe base and at each end thereof.

The wire 112 is secured to a binding post 131 at one end, and, aspointed out above, to

' mounted in an insulated nanner on the casing. A contact likewisenounted in and insulated from the casing provides 'or' a connection ofthe wire 136, which' is attached at its other end to the bnding post131. To the projections 132 and 135 may be attached a source of electriccurrent, the conventional plug (not shown) being slid thereover. i

It will be observed from the above description that when the lever 84 ismoved into contact with the strip 110 a circuit will be formed throughthe wire 113 to the strip 110, thence through the lever 84 (which may beof brass or any suitable conductive metal) through the wire 112andlthrough the series of small coils 129 thereby'heating them to agreat intensity. From the small cols the current will then flow through'the wire 136. The circuit is pointed out in the diagram shown in Figure16. e V

An insulation plate 137 is attached to the base of the casing 10 and isnclined forwardly and upwardly in front of the block 120. This plateserves to keep the intense heat from the pigment, which has been' jarredfrom the impression surface, in the drawer. V i Mounted on the rod 105'and adapted to rotate therewith is' a' gear`132. Adjacent the gear 132and mounted on the rod 105' and rotating therewith is the ratchet wheel139, provided with teeth 140'. A smaller gear 133, adapted to rotatewith the rod 133' is disposed beneath the rod 105'. The gear 132 mesheswith the gear 133. Gear 134,' larger than the gear 133, is also mountedto rotate with the rod 133'. The rod 140 carres a small gear 135rotating therewith The gear 135 meshes with the gear 134. Also mountedupon the rod 140 is a large gear 136, which in turn meshes with thesmaller gear 137, which ismounted to rotate with the rod 141. A fan ,138is also mounted upon the rod '141. The rods 141, 140 and 133' areadapted to rotate in the sides of the gear housing 20. j

It will thus `be seen by rotation of the rod 105' due to the step upgearing, the fan 138 may be rapidly rotated eventhough the rod 105' isturned slowly. The fan 138 serves in a sense as a governor.

Secured to the rod 105' is a lever 142 to which is pivotally attached apawl 143, which is adapted to engage with 'the ratchet teeth 140' uponthe rotation of the rod 105 in a counter-clockwise' direction.

Secured to one end of the rod 105' is an upstanding lug 144. A spring 29is' attached to the lug 144 by means of a'screw 145;- the other end ofthe'spring being adjustablyseeured to the plate member 27 by a screw 146as ponted-outebove.

. A :spring '1.47 maintains the let er- 66 in an npri ghtposition and isattached to a brecket 148 by means ofalu g 149 and to 'the lebody making'an outline thereon. The operator Will then grasp the hand1e`2l,` moveit in a counter-clockwise direction 'in the guide way By :such movementthe lug 79 on the 'base member 5 7 Will bear against the lug lnoving the'same outwardly i thereby di'scharging pignent from *the opening 46 onto `'the impressed surface.

The pignent is in'theform of a powder which n ay consist of asphaltum 6par-t; *by Volume; Wheat flour, 4; ;parte 'by -volulne'; 'talc powd'er,part by Volume and siiicon part by vohnn'e, although 'it 'is to beunderstood other suitable'pi-gment may be used wthout departing -fronthe spirit-of the invention. i

This movement :will `'be retar-ded {by 'the *lug 76 ridinfg over the'iever -77 and contactin-g With the recesse's 7 4: and 75 for-med inthe, `lever 72. Thu-s sufiicien't time Will be given tor the pigmenttobe applied to the impressed surface. Fur ther movement of the;Operating 'han`d1e"'will cause 'the impressed surface to dropupon'thecorrugetted 'strip of netal 118 and movement thereove'r Willspread the piginent upon the impressed surface and jar that which isune'ssenti-al in'to the dnawver 18 below it.

The iever '66 being 'moved in a count-erclockwise 'direction Will causethe extens-en or lug 67 to encounter the end of the levejr 107 'in'oving it upw-ardly, therehy moving the lever 102 upwardiy. The roller 106 *Will then be hr-ought against the lever- 84 novng --it in acoun'ter-clockwise direction 'until 'the L shaped end Will register With'the *recess '1 09 fonned in the level* 83. The *strip MO :will %by*this time be forced into contact With the lever 84. u i

Thus it Will be seen that the lever 84: is locked With the lever 83 and:can 1113 bereieas'ed by the roller 106 'hearing against the 'verticalportion :of the lever 83 and `mowbng the same :out otengagenent.

Will be in :a Vertical 'position paralie l to 'the v c'oi ls 129.Inviewo'f the' fact that t'h-'e metal i' np ressed surface bcing broughtinto pos-- tzron parallel to the Wire, the 'pgnent there- V on `W1ii befused :into the: surface.

lt shouid be noted *that after the pignen't is appled to this surface"on Whichthe inipression is made .further movement 'of the impressionsurface etain-ng nenber Will :bring tnto contact With the'iever 56,inov- 'ing it in a .clockwisedirection and returning `:the shde 42 bymeans of. a `finger 60 on the lever 47 to its forner position 'or thenext .operation as noted above.

. iatchet wheel 'MO', When the Operating hane die 21 has reached thelimit of: movement.

Assunring now that the lug :69 is locked :in the :extension 95 and thecoil spring) extenderi, the icoils 12941333 now heated due to thecircuit being fo'rn'ed and the pignent bengfused nto thempressedsurface. The cell spring 29 s constantly tendlng to rot'at'e themember 144: in a counter-clockwise `direction, thus the red 105' Wi libe ro-tated in a counterclockwise direction and through the series ofgear-s abc-ve described the fan .l-38 'wiilbe rotated. :Due 'to therotation of 'the rod 71 the iVBT 102 will -be moved :in

a :countenclockwise direction agai'st the level' 83, thereby novng the]ever 87 up- -Ward1y. The leter 87 Will !nove the lever- 90 in a counter-clookwise direction, thcre'by 'e'leasng the lug '69 froni the'extension :and pernittrng the !ever 66 to return 'to its 'normalposition due to 'the action =o`t the :co' l spring 147, the impressedsurface retainng member rdng up over the gud-e Way 119' aganst thehooked end porton thereof 120'. e v

From the above it will be observed that 'the 'impr-cssed surface 'isheld adjacent the heating means for a certain length of time, which maybe uared by movement of the knob shown 111 Fgure 5 pernntting the'impressed surface to be he'ld 10, 12, 15 or any number of secondsdesired (the numer- '21.15'10, '12 and 15 Only being shown by Way ofllustratio n). The tining n echanisn is composed mainiy of a series otgear-s whose operatiao nis controlied by a coil spring', the tension ofwhich may be vared at Wlu. "It

-is thus seen 'that `'the inpres's-i'on surface Will not be burned orcharred by ouerposure,

in viewot the 'fact that after the operator moves the handie to itslimit, further opa ;eratien or care on his part is dispensed w ith, :thehandle 'being returned :to normal :position *by 'means of aspring.

While the nve'nto-n has been ilustrated in What is co'nsidered its bestapplication it may have' other enbodhients e Without %ieparting from itsspirit and is not, therefore, limited to the structures shown in thedrawings.
